[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] Example 1

[0031] like Figure 1-Figure 5 As shown, the forearm rehabilitation trainer includes a horizontally placed base 1, an exercise box 2 slidably connected to the upper end of the base 1, and a rotating rod 3 rotatably connected to the exercise box 2;

[0032] Two parallel guide rails 25 are installed on the upper end of the base 1, and a linear slider 26 adapted to the two guide rails 25 is installed on the bottom end of the exercise box 2;

[0033] A bearing 24 is installed at the front end of the exercise box 2. The outer ring of the bearing 24 is fixedly connected to the exercise box 2. One end of the rotating rod 3 extends into the exercise box 2 and is fixedly connected to the inner ring of the bearing 24. The number of bearings 24 is preferably two, one bearing 24 is fixed to the front end of the exercise box 2 (not shown in the figure), and the outer ring of the other bearing 24 is fixed to the inner rear wall of the exercise box 2. The rotating rod 3 is fixedly connected to the inner rings of the two bearings 24. The arrangement of the bearings 24 increases the stability of the rotating rod 3.

[0034] The outer end of the rotating rod 3 is located outside the exercise box 2, and the outer end of the rotating rod 3 is rotatably connected to the handle 4 located outside the exercise box 2. The handle 4 is hollow inside and a traction rope 5 is fixedly installed. A finger sleeve 6 connected to the traction rope 5 is provided on the outside of the handle 4, and a first elastic piece 7 abutting the traction rope 5 is installed inside the handle 4. The first elastic piece 7 abuts the traction rope 5 to make the finger sleeve 6 fit to the outside of the handle 4.

[0035] It should be noted that the handle 4 and the axis of the rotating shaft of the rotating rod 3 are arranged vertically.

[0036] In this embodiment, a resistance mechanism for increasing the rotation resistance of the rotating rod 3 is installed in the exercise box 2. The resistance mechanism includes an adjusting rod 13 rotatably connected to the exercise box 2. The left part of the adjusting rod 13 at the rotation point is arc-shaped and located below the rotating rod 3. The left inner arc of the adjusting rod 13 faces the rotating rod 3. The right end of the adjusting rod 13 extends to the outside of the exercise box 2. A locking disk 14 with a locking groove 15 is coaxially fixedly connected to the rotating shaft of the adjusting rod 13. The number of the locking grooves 15 is at least two and they are surrounded by the outer side of the locking disk 14. A bottom column 16 is installed on the inner side wall of the exercise box 2, the length direction of which faces the locking disk 14. A coaxial locking pin 18 is slidably connected to the bottom column 16. A spring 17 is fixedly connected between one end of the locking pin 18 located in the bottom column 16 and the inner bottom end of the bottom column 16. The outer end of the locking pin 18 is adapted to the locking groove 15, and the outer end of the locking pin 18 is spherical.

[0037] The distance between the left side of the adjusting rod 13 and the rotating rod 3 can be adjusted by inserting the outer end of the locking pin 18 into different locking grooves 15. When it is necessary to increase the rotation resistance of the rotating rod 3, the right end of the adjusting rod 13 is moved to make its left side abut against the rotating rod 3 to increase the rotation resistance of the rotating rod 3. At the same time, as a conventional technical means for those skilled in the art, an object with a certain elasticity (such as rubber or a cotton layer with a certain thickness) can be bonded to the inner arc of the left side of the adjusting rod 13 to avoid hard contact between the rotating rod 3 and the adjusting rod 13, while also increasing the resistance; different resistances can be formed by inserting the locking pin 18 into different locking grooves 15, which is convenient for adapting to recovery exercises at different stages.

[0038] In this embodiment, in order to prevent the exerciser's arms from hanging in the air, a forearm support bracket 23 is fixedly installed at one end of the base 1 close to the handle 4. When in use, the forearm is placed on the forearm support bracket 23 to form a fulcrum, thereby reducing fatigue during exercise.

[0039] Working principle: first, place the base 1 on a flat table, and the exerciser places the forearm on the forearm support 23, and performs recovery exercise by holding the handle 4 and rotating it left and right. Before or during exercise, the adjustment rod 13 can be adjusted to make the rotating rod 3 have different resistances to achieve different training intensities; after performing one or more sets of left and right rotations, the exerciser stops rotating, and the exerciser's palm begins to swing left and right through the wrist. During the left and right swinging process, the exercise box 2 will move back and forth with the exercise to allow the handle 4 to swing; after performing one or more sets of left and right swings, the exerciser stops rotating, and the exerciser's palm begins to swing left and right through the wrist. During the left and right swinging process, the exercise box 2 will move back and forth with the exercise to allow the handle 4 to swing; After training, the exerciser inserts the four fingers except the thumb into the finger cuff 6, and exercises by continuously opening the fingers and holding the handle 4. During the process of opening and holding the fingers (including the thumb), as the distance between the finger cuff 6 and the handle 4 increases, the abutment force applied by the first spring piece 7 to the traction rope 5 becomes greater, and as the distance between the finger cuff 6 and the handle 4 decreases, the abutment force applied by the first spring piece 7 to the traction rope 5 becomes smaller, thereby forming resistance in the process of opening the fingers and increasing the exercise effect. After the above three sets of exercises, the muscles in the forearm can be exercised in a coordinated manner to avoid inadequate exercise.

[0040] In combination with the above, this application can coordinately exercise different muscles in the forearm through the arrangement of the base 1, the exercise box 2, the handle 4, the finger sleeve 6, the first spring piece 7 and the first traction rope 5, effectively solving the current problem that the muscles on the forearm cannot be coordinated as a whole.

[0041] Example 2

[0042] like Figure 1 、 Figure 3 and Figure 5 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. When the palm swings left and right, in order to adapt to the exercise intensity of people exercising at different stages, second elastic members are respectively installed on both sides of the rotating rod 3. The second elastic members include adjusting bolts 8 rotatably connected to both sides of the rotating rod 3. The two adjusting bolts 8 are fixedly connected to a second elastic piece 9 with one end abutting against the side of the handle 4. The two adjusting bolts 8 are meshed. A shell 10 is fixedly connected to the rotating rod 3 to cover the two adjusting bolts 8. Adjustment openings 11 are provided on the left and right side walls of the shell 10. The side wall of the bolt cap in the adjusting bolt 8 is located outside the adjustment opening 11. An adjusting bolt 12 abutting against the upper end of one of the adjusting bolts 8 is threadedly connected to the shell 10; by loosening the abutment of the adjusting bolt 12 on the adjusting bolt 8, the abutment force of the second elastic piece 9 on the handle 4 is adjusted by rotating the side wall of the adjusting bolt 8, so as to form different sizes of resistance, and then tightening the adjusting bolt 12 to fix the adjusting bolt 8.

[0043] Example 3

[0044] like Figure 1As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. In this embodiment, in order to facilitate use by people of different heights, a height adjustment mechanism is installed on the base 1. The height adjustment mechanism includes a first mounting seat 19, a fixing rod 20 and a second mounting seat 21 connected in sequence from top to bottom. There are two fixing rods 20 and they are arranged in parallel. The two fixing rods 20 are both passed through the base 1. A through hole adapted to the fixing rod 20 is opened on the base 1. The base 1 can be lifted and moved up and down along the fixing rod 20. A positioning bolt 22 abutting against the fixing rod 20 is threaded on the base 1. The base 1 is fixed at different heights by tightening the positioning bolt 22 to abut against the fixing rod 20. The length direction of the rotating rod 3 is parallel to the upper end of the base 1, and the length direction of the rotating rod 3 is perpendicular to the length direction of the fixing rod 20.

[0045] In this embodiment, the second mounting base 21 is first fixedly installed on the desktop, and two fixing rods 20 are vertically fixedly installed on the upper end of the second mounting base 21. The base 1 is installed on the fixing rods 20, and the base 1 is moved to a suitable height and the positioning bolts 22 are tightened. Then, the first mounting base 19 is fixedly installed on the upper ends of the two fixing rods 20. When the height of the base 1 needs to be adjusted, the positioning bolts 22 are directly loosened, moved into place, and then tightened.
